A new donor (D)-acceptor (A) type naphthalene-based oxazepine-containing fluorophore, OXN-1, is reported, which shows unusually high stability in various environments. Its photophysical properties and structural stabilities under harsh conditions are thoroughly examined. The high stability of OXN-1 is explained by quantum chemical calculations. Its exceptional bioimaging capabilities for cells with low cytotoxicity are verified. In addition, its deep tissue imaging ability with two-photon microscopy (TPM) is evaluated.
